Method and apparatus for updating map data, and computer-readable medium storing program for executing the method

Abstract

A method and an apparatus for easily updating map data in real time, using a device employing map data or a navigation system, through a transport protocol expert group (TPEG) service, and a computer-readable medium storing a computer program for executing the method, as provided. The method includes determining if the map data has changed using location information received from at least one of a broadcasting network, the Internet, and a transmission medium; and updating the map data based on the location information if the map data has changed.

Description

BACKGROUND OF THE INVENTION[0001]This application claims priority from Korean Patent Application No. 10-2004-0092337, filed on Nov. 12, 2004, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.[0002]1. Field of the Invention[0003]Methods and apparatuses consistent with the present invention relate to using map data, and more particularly, to updating map data in a device employing the map data or a navigation system.[0004]2. Description of the Related Art[0005]A device employing map data or a navigation system stores map data when the device or navigation system is manufactured. The device may be a portable phone, a portable device, such as a notebook computer, or a desktop computer. However, map data changes over time. Thus, a device manufacturer or a navigation system manufacturer periodically provides the map data online or offline, or provides the map data online or offline whenever the map data of a specific a...

Benefits of technology

[0010]Methods and apparatuses according to exemplary embodiments of the present invention easily update map data in real time, in a device employing the map data or a navigation system, using a transport protocol expert group (TPEG) service. A computer-readable medium may store a computer program for executing such a method.

Problems solved by technology

However, map data changes over time.

Since it is necessary to update the map data stored in the device or the navigation system, the user cannot obtain updated map data in real time and must pay a separate communication fee or a data usage fee in order to download the updated map data.

Additionally, the user cannot use the device or the navigation system during the updating process.

For example, a user cannot update the map data stored in a portable phone while using the portable phone, but instead must wait until after hanging up the phone to update the map data.
